This treatment provides a base layer for painting or powder coating, providing greater adhesion.

Iron Phosphate


Iron phosphate is a preparation process for metal parts. It involves immersing the metal part in an iron phosphate bath, which contains iron and phosphate ions. A chemical reaction takes place, resulting in the deposition of a thin layer of iron phosphate. This coating provides a porous surface that helps to improve the adhesion of the paint or powder coat, making it an ideal base layer for metal preparation. In addition, the iron phosphate coating acts as a barrier that protects the underlying metal from moisture and other corrosive elements, helping to extend the service life of the treated parts.

Please note, Sub Source only offers iron phosphate as a complete paint or powder coat process. It is not available as a standalone dip process.
